I'll answer #4, since that's the one that I'm most familiar with. I assume by "old control system parts" you mean older versions of the KOP electronics (like the cRIO will be after this year). I think your best option is to use them for a practice/demo bot. They still work fine (I'd assume), so there's no point in getting rid of them. Building a robot that you can use for demos instead of your competition bot can make things a lot easier: you can customize it to make it better for demos (higher clearance, more weather-proof-ness, etc.) and you don't have to take your competition bot to demos, which can be nice if you have offseason events that you're planning on attending. We drove our 2013 bot hard at several demos between St. Louis and our offseason events, and had to do an overhaul in order to make it competition-worthy again.

If you don't feel like doing that, you could try selling them, but I'm not sure how much luck you'd have there.
